Chinese Graphite for Powder Metallurgy

We provide the powder metallurgy industry with quality natural flake graphite products to be used as release agents, alloy component additives, sintering control, ferrous and bronze (non-ferrous) mixes, bearing, iron-based steel matrix, and other applications where carbon control and free graphite are important.

Our graphite powders contain many unique physical properties, such as: highly crystalline structure, high purity, temperature stability, lubricity, and superior electrical and thermal conductivity.

Our production process entails the use of advanced equipment that results in a more uniform particle distribution and purity, solving several problems found in the PM industry.
